Apple needs a new Power Supply.
The Apple power brick is the worth design Apple ever made! The puck was a by far better design. I throw out and buy numerous new bricks every year for our staff. The flip up fingers are the downfall of this design. The best design is to coil up the cable naturally as seen in the image below.
Those faculty that coil the cable up like this I rarely have to buy new bricks for. The brick design has been Apple's biggest mistake along with the MagSafe 2 adapter. Come on Apple, lets have a better PS! You make sleek commuters, how about a proper functioning PS like the old puck.
